mac80211: implement SMPS for AP
When the driver requests to move to STATIC or DYNAMIC SMPS,
we send an action frame to each associated station and
reconfigure the channel context / driver.
Of course, non-MIMO stations are ignored.
The beacon isn't updated. The association response will
include the original capabilities. Stations that associate
while in non-OFF SMPS mode will get an action frame right
after association to inform them about our current state.
Note that we wait until the end of the EAPOL. Sending an
action frame before the EAPOL is finished can be an issue
for a few clients. Clients aren't likely to send EAPOL
frames in MIMO anyway.
When the SMPS configuration gets more permissive (e.g.
STATIC -> OFF), we don't wake up stations that are asleep
We remember that they don't know about the change and send
the action frame when they wake up.
When the SMPS configuration gets more restrictive (e.g.
OFF -> STATIC), we set the TIM bit for every sleeping STA.
uAPSD stations might send MIMO until they poll the action
frame, but this is for a short period of time.

Enabling and disabling SSP debug mode is useful for development. This
adds a debugfs entry that allows to configure the SSP debug mode.
On purpose this has been implemented as debugfs entry and not a public

ath9k: add TX99 support
TX99 support enables Specific Absorption Rate (SAR) testing.
SAR is the unit of measurement for the amount of radio frequency(RF)
absorbed by the body when using a wireless device. The RF
exposure limits used are expressed in the terms of SAR, which is a
measure of the electric and magnetic field strength and power density
for transmitters operating at frequencies from 300 kHz to 100 GHz.
Regulatory bodies around the world require that wireless device
be evaluated to meet the RF exposure limits set forth in the
governmental SAR regulations.
In the examples below, for more bit rate options see the iw TX bitrate
setting documentation:
http://wireless.kernel.org/en/users/Documentation/iw#Modifying_transmit_bitrates
Example usage:
iw phy phy0 interface add moni0 type monitor
ip link set dev moni0 up
iw dev moni0 set channel 36 HT40+
iw set bitrates mcs-5 4

ath9k: check for NULL rate when using ieee80211_get_rts_cts_rate()
ieee80211_get_rts_cts_rate() can return NULL, so don't rely
on its members when it does return NULL.

ath: add support for proper dynamic regulatory hints
This enables support for dynamic user regulatory hints.
This is enabled only when CFG80211_CERTIFICATION_ONUS
is selected. For US and JP this is explicitly disabled
unless the systems are being used for strict controlled
testing.

ath: split user and driver reguluatory hint parsing
On the regulatory notifier split up the parsing of the
hints coming from drivers or user. We'll treat these
separately.
